// -=- SocketManager.h
|
|
|
|
// Socket manager class for Win32.
|
|
// Passed a network::SocketListener and a network::SocketServer when
|
|
// constructed. Uses WSAAsyncSelect to get notifications of network
|
|
// connection attempts. When an incoming connection is received,
|
|
// the manager will call network::SocketServer::addClient(). If
|
|
// addClient returns true then the manager registers interest in
|
|
// network events on that socket, and calls
|
|
// network::SocketServer::processSocketEvent().
